The PG_VERSION_NUM is not available in intended public PostgreSQL
headers unless the pg_config.h is included or the PostgreSQL server
development headers are installed separately. This instead resorts to
checking for the PGVerbosity enum value. The PQERRORS_SQLSTATE was added
to PostgreSQL 12.0. At the time of writing, on Windows, PostgreSQL is at 11.4 so
it is not defined there yet.
Using PQSocketPoll to poll on a connection's socket.
Returns immediatly is there no event expected on read and write.
Other than that, it is a thin wrapper on top of poll, thus reflecting
its return value.

pg_put_copy_data allows to send COPY commands to the server.
pg_put_copy_end signals the end of the n commands.
Both return 3 states ; 1, 0 and -1 when 1 is success, 0 the buffer queue
is full then -1 for errors.

Previously, pg_select did not allow unconditional selection, where an
empty ids array would result in a function failure.
This patch implements two changes:
- Make the ids array an optional parameter.
- Allow the ids array to be empty.
In both cases, unconditional selection happen, which is equivalent to
pg_query('SELECT * FROM <table>;').
Two test cases were added to test the aforementioned changes.

output to check possible regressions.

This is an error that slipped in via 8d37c37bcd.
pg_unescape_bytea() did not accept null in PHP 7.4, and it is not
meaningful for it to accept null now -- it will always fail, and now
with a misleading OOM message.
The same error condition is a ValueError in mysqli, be consistent.
Additionally, do not display the argument name for these errors.
As the signatures are overloaded, the argument name may not match
the meaning at all.
The implementation did not check for PQunescapeBytea failure
correctly, because it checked for a null pointer after estrndup,
which certainly cannot happen. Inspection of the PGunescapeBytea
implementation has shown that this function can only fail on OOM,
so let's check for that explicitly and remove false as a possible
return type.
While we're here, avoid an unnecessary copy of the result.
